Events Tracked for Token Exchange

For a token exchange, you can track the following events:

1. AttachmentAdded: This event can be retrieved and parsed using the getAttachments method.
2. TransferSingle and TransferBatch: These events are used to fetch balances for all tokenId and address pairs using the getTokens method.
3. ExchangeRefuted and RefutationNullified: These events are used to fetch the refutation timeline using the refutationsTimeline method.

These events help in tracking various activities and changes within the token exchange contract.
